Technical field

The present invention relates to the communications field, strengthen transmission method and the device of physical hybrid automatic repeat request indicator channel (enhanced Physical Hybrid ARQ Indicator Channel, referred to as ePHICH) in particular to one.

Background technology

Long Term Evolution (Long Term Evolution, referred to as LTE) system is the essential planning of third generation partnership (3rd Generation Partnership Project, referred to as 3GPP).When LTE system adopts regular circulation prefix (Cyclic Prefix, referred to as CP), the up/down row symbol that comprises 7 length in a time slot; When LTE system adopts expansion CP, the up/down row symbol that comprises 6 length in a time slot.

In LTE system, define following several physical channel:

Physical Broadcast Channel (Physical Broadcast Channel, referred to as PBCH): the information of this channel bearing comprises: the cycle of the frame number of system, the downlink bandwidth of system, physical mixed retransfer channel and the parameter N for definite physical hybrid automatic repeat request indicator channel (Physical Hybrid ARQ Indicator Channel, referred to as PHICH) channel group number _g∈ { 1/6,1/2,1,2};

Physical Multicast Channel (Physical Multicast Channel, referred to as PMCH): be mainly used in supporting multicast single frequency network (Multicast Broadcast over Single Frequency Network, referred to as MBSFN) business, multimedia time-frequency information is broadcasted to multi-user.PMCH can only be in MBSFN subframe and the transmission of MBSFN region;

Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH): for bearing downlink transmission data;

Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH): for carrying uplink and downlink schedule information, and uplink power control information.PDCCH in LTE R8, R9 and R10 is mainly distributed in front 1,2,3 or 4 OFDM (Orthogonal Frequency Division Multiplexing of a subframe, referred to as OFDM) symbol, concrete distribution need to configure according to the port number of different subframe type and public reference signal (Common Reference Signal or Cell-specific Reference Signal, referred to as CRS).As shown in table 1, provide respectively according to the downlink resource piece number of the port number configuration of different subframe type and CRS be greater than 10 and be not more than the OFDM number of symbols that 10 PDCCH takies;

The OFDM number of symbols that table 1PDCCH takies

Physical Control Format Indicator Channel (Physical Control Format Indicator Channel, referred to as PCFICH): the information of carrying is used to indicate the number that transmits the OFDM symbol of PDCCH in a subframe, on first OFDM symbol of subframe, send, place frequency location is determined by system descending bandwidth and cell ID (Identity, referred to as ID);

PHICH: for carrying acknowledgement/non-acknowledgement (ACK/NACK) feedback information of uplink transmission data.Number, the time-frequency position of PHICH can be determined by the system message in the Physical Broadcast Channel of the descending carrier at PHICH place (Physical Broadcast Channel, referred to as PBCH) and community ID;

Physical uplink data sharing channel (Physical Uplink Shared Channel, referred to as PUSCH), for carrying uplink transmission data.

The transmission of LTE physical layer PHICH channel is organized with the form of PHICH group, the identical time-frequency domain physical resource of multiple PHICH channel occupancies in 1 PHICH group, the multiplex mode of employing orthogonal spreading sequence.At regular circulation prefix (Normal Cyclic Prefix, referred to as Normal CP) situation under, adopting spreading factor is 4 in conjunction with I/Q (In-phase/Quadrature, inphase quadrature) two-way BPSK (Binary Phase Shift Keying, binary phase shift keying) modulation multiplex mode, 1 PHICH group comprises 12 modulation symbols, take 3 resource unit group (Resource Element Group, referred to as REG), multiplexing 8 PHICH channels.At extended cyclic prefix (Extended Cyclic Prefix, referred to as Extended CP) time, for the stronger wireless channel of frequency selectivity, adopting spreading factor is 2 multiplex modes in conjunction with I/Q two-way BPSK modulation, 1 PHICH group comprises 6 modulation symbols, multiplexing 4 PHICH channels, now, 2 PHICH groups take the physical resource of 3 REG jointly.

On frequency domain, 13 REG corresponding to PHICH group adopts distributed mapping mode, to obtain diversity gain.In time, there are conventional and two kinds of resource mapping method of expansion the PHICH duration (PHICH duration).In the time of usual manner, PHICH is mapped on first OFDM symbol of subframe; And as Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH) length be 3 o'clock (or at the MBSFN of mixed carrier subframe or time division duplex (Time Division Duplex, referred to as TDD) in special subframe, PDCCH length is 2 o'clock), PHICH can be configured to the mode of expansion, and now PHICH will be distributed on the shared multiple OFDM symbols of PDCCH.

In LTE, adopt public reference signal (Specific Reftrence Signals, referred to as CRS) to carry out measurement and the demodulation of pilot tone, all users use CRS to carry out channel estimating.The concrete pretreatment mode that the data that need transmitting terminal additionally to notify receiving terminal to launch while adopting this CRS adopt, and the expense of pilot tone is larger.In multi-user's multiple-input and multiple-output (Multi-user Multi-input Multi-output, referred to as MU-MIMO), because multiple terminals are used identical CRS, cannot realize the orthogonal of pilot tone in addition, therefore be unable to estimate interference.In LTE-A, in order to reduce pilot-frequency expense, two class reference signals are defined respectively: demodulated reference signal (Demodulation Reference Signal, referred to as DMRS) and channel state information reference signals (Channel State Information Reference Signal, referred to as CSI-RS), wherein DMRS is for the demodulation of PDSCH.For channel condition information (Channel State Information, referred to as CSI) measure CSI-RS, be mainly used in channel quality instruction (Channel Quality Indicator, referred to as CQI), pre-coding matrix instruction (Precoding Matrix Indicator, referred to as PMI), the reporting of the information such as order instruction (Rank Indicator, referred to as RI).Special CSI-RS signal is referred to as zero energy channel state information reference signals (Zero Power Channel State Information Reference Signal in CSI-RS, also to comprise a class, referred to as ZP-CSI-RS), be confirmed as for not sending any reference signal sequence or data in the resource of ZP-CSI-RS, otherwise be referred to as non-zero power channel state information reference signals (Non-Zero Power Channel State Information Reference Signal, referred to as NZP-CSI-RS) signal.The effect of ZP-CSI-RS is mainly to disturb in order to measure more accurately adjacent area.

Fig. 1 is the schematic diagram of LTE system Physical Resource Block (Resource Block, referred to as RB).As shown in Figure 1, a resource element (Resource Element, referred to as RE) be a subcarrier in an OFDM symbol, and a descending RB is made up of continuous 12 subcarriers and 7 continuous (being 6 when extended cyclic prefix) OFDM symbols.A Resource Block is 180kHz on frequency domain, is the time span of a time slot in time domain.Carry out resource and divide timing, can taking two Resource Block in a subframe (corresponding two time slots) (also referred to as Physical Resource Block to) distribute as base unit.Fig. 2 is the right schematic diagram of LTE system Physical Resource Block, also shows the resource location of corresponding PDCCH, CRS and DMRS etc. in Fig. 2.

Under LTE-A heterogeneous network, owing to existing compared with strong jamming between dissimilar base station, consider the interference problem of macro base station (Macro eNodeB) to micro-base station (Pico), propose to utilize the method that resource is mourned in silence to solve the mutual interference problem between dissimilar base station, the concrete resource method of mourning in silence can be divided into: (Muting) method of mourning in silence (such as the method for gap frame (Almost Blank Subframe, referred to as ABS)) based on subframe and the method for mourning in silence based on resource element (for example CRS mourn in silence method).The existing method of utilizing method that resource is mourned in silence to solve the mutual interference problem between dissimilar base station, not only increase the waste of resource, and bring great restriction for dispatching, particularly in the time of the ABS configuration of considering Macro eNodeB, if the distribution of Pico is more, the ABS of Macro eNodeB configuration is more, has brought larger impact to Macro eNodeB, in increasing the wasting of resources, has increased scheduling time delay; And, although can reduce the interference of different control channel data resources under ABS for control channel, cannot solve the interference problem of CRS resource and data resource, cannot solve the interference between data resource for the method for the CRS that mourns in silence.In addition, the method backwards compatibility is bad, when having increased access delay, may need more standardization effort.

May introduce more user in the LTE R11 stage sends in MBSFN subframe, will cause like this off-capacity of the down control channel that 2 OFDM symbols of MBSFN configuration can carry, in order to ensure the backwards compatibility to R8/R9/R10 user, need in PDSCH resource, open up the resource of new control information transmission, and introduce coordinated multipoint transmission (Coordinated Multiple Point Transmission and Reception in the R11 stage, referred to as CoMP) technology, the mode that this technology can be divided by sky solves the interference problem between dissimilar community, and save resource overhead, the wasting of resources that having avoided mourns in silence brings, reduce the restriction to scheduling.But, be that the method that cannot divide by sky addresses this problem according to the mode of traditional time-domain down control channel.

Pass through the enhancing to PDCCH in the LTE R11 stage, mark off a part of resource in original PDSCH region and transmit the Physical Downlink Control Channel of enhancing (enhanced Physical Downlink Control Channel, referred to as ePDCCH), so just can improve the number of capacity and the while scheduling user's set of PDCCH, wherein ePDCCH is by strengthening physical control channel unit (enhanced Control Channel Element, referred to as eCCE) composition, and each eCCE is by multiple enhancing resource element groups (enhanced Resource Element Group, referred to as eREG) composition, and the Physical Resource Block of each ePDCCH of distributing to is to being divided into 16 eREG, for example each PRB (Pyhsical Resource Block under conventional CP, physical resource is fast) the eREG dividing mode of centering is as shown in Figure 3.

In LTE R12, due to new carrier type (New Carrier Type, referred to as NCT) and the introducing of small-cell (small cell), traditional downlink physical control channel region will be excluded, and carrying out the transmission of physical down control signal based on ePDCCH, this just causes existing PHICH design cannot be applicable to new frame structure.In Low cost MTC, need to support the wide reception technique of small band in addition, but because traditional time-domain down control channel mode is that control channel information is distributed on full bandwidth discretely, therefore cannot support well the wide reception of small band.

Therefore, problem that cannot be applicable in capacity problem, interference problem and the NCT existing for above-mentioned conventional P HICH and Low cost MTC scene, the physical down HARQ indicating channel that needs consideration to strengthen.About the design problem of the physical down HARQ indicating channel strengthening, effective solution is not yet proposed at present.

Mode four:

All PRB resources that can be used for transmitting ePDCCH all can be used for ePHICH transmission, and therefore network side is without using the extra signaling that uses to notify ePHICH transmission candidate running time-frequency resource.

Preferably, the part resource that can be used for transmitting in the PRB resource of ePDCCH can be used for ePHICH transmission.In this case, just need which the part resource (for example which eCCE or eREG etc.) in these PRB resources of notification terminal to can be used for ePHICH transmission.

Mode five:

In the time that the PRB of whole downlink system full bandwidth resource all can be used for ePHICH transmission, whole downlink system full bandwidth is divided into Np group based on PRB, end side is used wherein a certain group of PRB to transmit its ePHICH, and multiple users share one group of PRB resource.In every group of PRB resource, can carry out again the division of ePHICH running time-frequency resource group, be implemented as follows and state described in step 2.

Network side can by high-level signaling and/or physical layer signaling notification terminal side under it ePHICH transmission candidate resource belong to which PRB group.

Step 1 situation two, determines the eCCE resource that can be used for transmitting ePHICH in ePHICH PRB resource, specifically comprises following at least one mode:

Preferably, network side is by indicate the parameter of PHICH duration or the eCCE resource that signaling takies to end side instruction ePHICH simultaneously in prior art.Be 1 bit system signaling as indicated the signaling of PHICH duration in prior art, this signaling can be used for can be used in each ePHICH PRB resource the notice of the eCCE resource of ePHICH transmission, as shown in table 2:

In the signaling of table 2PHICH duration, in bit value and ePHICH PRB resource, can be used for the corresponding relation of the eCCE resource of ePHICH transmission

If also have remaining eCCE resource in described ePHICH PRB resource except can be used for the eCCE resource of ePHICH transmission, these remaining eCCE resources can be used for transmitting ePDCCH or PDSCH.

Mode two:

The more than one eCCE resource of only making an appointment in each ePHICH PRB resource can be used for ePHICH transmission, described in make an appointment refer to network side and end side acquiescence or do not need by signaling.

Preferably, above-mentioned more than one eCCE resource of making an appointment is first eCCE in each ePHICH PRB resource or the first two eCCE or last eCCE or latter two eCCE, or is the whole eCCE in this ePHICH PRB resource.

In described ePHICH PRB resource, except can be used for the eCCE resource of ePHICH transmission, if also have remaining eCCE resource, these remaining eCCE resources can be used for transmitting ePDCCH or PDSCH.

In each ePHICH PRB resource, the eREG resource of preferentially selecting eREG index n to meet nmodQ=i is transmitted for ePHICH, and wherein Q is greater than 1 and be less than 16 integer, preferably, Q=2 or 4 or 8.For example, the in the situation that of Q=4, eREG index is { 0,4, the eREG resource first of 8,12} is preferentially selected for ePHICH transmission, and second preferentially to take eREG index be { 1, the eREG resource of 5,9,13}, the 3rd preferentially to take eREG index be { 2,6,10, the eREG resource of 14}, the 4th preferentially to take eREG index be { 3,7, the eREG resource of 11,15}.

In addition preferentially, in each eREG resource that meets nmodQ=i, the priority of eREG resource reduces successively according to eREG index n order from small to large.Meeting in all eREG of this condition of nmod Q=0, the priority of eREG0 is the highest, is secondly eREG Q, then is secondly eREG2Q, by that analogy.

Network side, according to the demand of definite ePHICH resources such as customer volume, upstream data amount or system parameters, then configures which eREG resource in each ePHICH PRB resource according to above-mentioned priority and can be used for ePHICH transmission.For example, the in the situation that of Q=4, if determining the demand of ePHICH resource, network side is about that in each ePHICH PRB resource, to take 1 eREG just much of that, network side will have and only have eREG0 to can be used for ePHICH transmission in each configuration ePHICH PRB resource; If network side determines the demand of ePHICH resource and be about that to take 2 eREG in each ePHICH PRB resource just much of that, network side will have and only have eREG0 and eREG4 to can be used for ePHICH transmission in each configuration ePHICH transmission candidate resource; If network side determines the demand of ePHICH resource and be about that to take 3 eREG in each ePHICH PRB resource just much of that, network side will have and only have eREG0, eREG4 and eREG8 to can be used for ePHICH transmission in each configuration ePHICHPRB resource; If network side determines the demand of ePHICH resource and be about that to take 4 eREG in each ePHICH PRB resource just much of that, network side will have and only have eREG0, eREG4, eREG8 and eREG12 to can be used for ePHICH transmission in each configuration ePHICH PRB resource; If network side determines the demand of ePHICH resource and be about that to take 5 eREG in each ePHICH PRB resource just much of that, network side will have and only have eREG0, eREG4, eREG8, eREG12 and eREG1 to can be used for ePHICH transmission in each configuration ePHICH PRB resource; If network side determines the demand of ePHICH resource and be about that to take 6 eREG in each ePHICH PRB resource just much of that, network side will have and only have eREG0, eREG4, eREG8, eREG12, eREG1 and eREG5 to can be used for ePHICH transmission in each configuration ePHICH PRB resource; By that analogy.

In ePHICH PRB resource, preferentially select eREG index n to meet eREG resource for ePHICH transmission, wherein: Q ' is for being greater than 1 and be less than 16 integer, j ∈ [0,1 ..., Q '-1], represent to round downwards.Preferably, Q '=2 or 4 or 8.For example, the in the situation that of Q '=4, eREG index is { 0,1, the eREG resource first of 2,3} is preferentially selected for ePHICH transmission, and second preferentially to take eREG index be { 4, the eREG resource of 5,6,7}, the 3rd preferentially to take eREG index be { 8,9,10, the eREG resource of 11}, the 4th preferentially to take eREG index be { 12,13, the eREG resource of 14,15}.

In addition preferentially, meeting all eREG resources in, the priority of eREG resource reduces successively according to eREG index n order from small to large.For example meeting in all eREG of this condition, the priority of eREG0 is the highest, is secondly eREG1, then is secondly eREG2 (Q ' > 2), by that analogy.

Network side, according to the demand of definite ePHICH resources such as customer volume, upstream data amount or system parameters, then can be used for ePHICH transmission according to which eREG resource in above-mentioned priority configuration ePHICH PRB resource.For example, the in the situation that of Q=4, if determining the demand of ePHICH resource, network side is about that in ePHICH PRB resource, to take 1 eREG just much of that, network side will have and only have eREG0 to can be used for ePHICH transmission in each configuration ePHICH PRB resource; If network side determines the demand of ePHICH resource and be about that to take 2 eREG in each ePHICH PRB resource just much of that, network side will have and only have eREG0 and eREG1 to can be used for ePHICH transmission in each configuration ePHICH PRB resource; If network side determines the demand of ePHICH resource and be about that to take 3 eREG in each ePHICH PRB resource just much of that, network side will have and only have eREG0, eREG1 and eREG2 to can be used for ePHICH transmission in each configuration ePHICH PRB resource; If network side determines the demand of ePHICH resource and be about that to take 4 eREG in each ePHICH PRB resource just much of that, network side will have and only have eREG0, eREG1, eREG2 and eREG3 to can be used for ePHICH transmission in each configuration ePHICH PRB resource; If network side determines the demand of ePHICH resource and be about that to take 5 eREG in each ePHICH PRB resource just much of that, network side will have and only have eREG0, eREG1, eREG2, eREG3 and eREG4 to can be used for ePHICH transmission in each configuration ePHICH PRB resource; If network side determines the demand of ePHICH resource and be about that to take 6 eREG in each ePHICH PRB resource just much of that, network side will have and only have eREG0, eREG1, eREG2, eREG3, eREG4 and eREG5 to can be used for ePHICH transmission in each configuration ePHICHPRB resource; By that analogy.
